To all whom it may concern.'

Be it known lthat I, JAMES DoMRoUsKr, residing in Milwaukee, in the count of Milwaukee and State of Wisconsin, ave invented new and useful Im rovements in Pin-Setters, of which the fol owing is a deseription, reference being had to the accompanying drawings, which are a part. of this Ispecification.

M y invention has relation to improvementsI in pin Setters, that is to say, to mechanism for setting the pins used in the gaines of nine-pins and tenips.

The object of the invention isto provide an improved means for accurately and' quickly setting the pins mechanically.

With the above primary object, and other incidental objects, in view, the invention consists of the devices and parts, or their equivalents, as hereinafter set forth.

ln the accompanying drawing, Figure 1 is an inverted plan view of the platform whieh carries the pin-holding mechanism. Fig. 2 is a rear view of Fig. 1, parts broken away; Fig. 3 is a detail View of one of the pin-holding devices or cages, showingthe wings turned to open position; Fig. 4 is a perspective View in detail of one of the pinholding devices or cages, the wings thereof being shown in closed position; Fig. 5 is an elevation at right anglesit'o Fig. 2, parts broken away, and showing the platform partly raised from the floor, and the wings ot the pin-holding devieesinelosed position; Fig. is a side elevation ot the platforivn which carries the pin-holding devices, sliow ing the wings of said pin-holding devices in open position; Fi f. 7 is a plan View et' a fragment: of therp atform', and a vfragment of the upper frame; Fig. 7 is a detail View ot the main operating lever and allied ineelianisin; and Fig. 7" is a detail view ofthe mechanism for operating the :front and reni' ingsof the rear'line or row ot pin-holding devices or cages.

Referring to the drawings, the numeral 8 indieates va platform, preferably of triangular shape, and provided with` lines of openings therethrough. llie openings, of the rear line. which are four in number, are indicated by the numeral 9the openings of the next line in advance, which are three in number, by the numeral 10, the openingsI of the next succeeding line in advance which are two iu. number, by the numeral 11, and t the forward single opening by the Inumeral 12. 1

A series of apertured plates 13 are provided, one for each platform opening. The upper side of each plate is provided with an upwardly extending curved guide 14, and the under side of each plate at diainetrically opposite points, is provided withdepeiidingy wings 1G, 16 attached to the separate plates 13. It. is obvious, however, that withoutany departure from the spirit and scope Aof the invention, the plates 13 could be entirely disl'iensed with, and the guides secured directly to the platform and extend upwardly from the edges of the openings of said platform, and that the wings could be pivoted to lugs extendinfr downwardly from the uiider side of the p atforin,

The rear wings of the rearinost line of pin-holding devices are connected so as to be swung in unison by means of a bar 17, preferably of right angular form, and the forward wings of said rearmost line of pinliolding devices are connected by a similar' har 1.8. 'The rear wings of the next line of )in-holdin devices are-connected so as to e swun in unison by means of a bar 19, referab y of right angular form, and the orward wings of said line of pinfliolding y struction, l prefer to have the guides 14- and devices are connected by a similar bar 20.

The rear wings of the next line of pin-holding devices are connected by an angle bar 21, and the forward Wings o said line by an angle-bar 22. The rear wing of the for- Ward single pin-holding device hassecured thereto a very short angle bar 23, and the A yforward winer thereof has connected thereto a somewhat-rlonger angle bar 24. On the 1 form. Straddling ainedial sition shown y recess 33 in the platform. The arm which is provided with this lug 32 is heavier than the mally in the Figi' 5 intended that the front and rear wings of,

', the rear line of pin-holding this operation,

ated from one main lever 27, said lever ex\ tending'through an opening in the latform, so that the handle ortion thereo is above the platform, and t e lower portion of the 5 lever below the platform, the said lower porivoted between brackets 28, 28 rom the under side of the platpoint of the le: ver, and pivoted to said' medial point are tion being depending 10 two links 29, 29, said liliks extending forwardly and receiving pivotally between their forward ends the lower end of a crank 30 rigidly mounted on and depending from the rock-shaft 26. The upper` handle portion of 15 the lever has pivoted thereto a dog or catch 31, preferably in the form of a bell-crank lever, one arm thereof being provided with a vdepending lug 32 which is adapted, when the dog or catch is turned down to the poin Figs. 5 and 7, to engage a other arm of the dogfso that said dog is norlocking position. It is 35 a crank-34 depending from the rock-shaft.

Pivotally connected to the lower end of this 'crank is a link 35 which extends rearwardly, and yivotally connects to the rear angle bar 17 o the rear 4line of pin-holding devices.y 40 Also pivotally connected to the crank 34 is another link` 3G which extends rearwardly at an upward slant and pivotally connects with one/end of a medi-ally pivoted lever 37.

To the opposite'end of said medially pivoted y, lever is pivotally jointed a link 38 which eX- tends forwardly and pivotally connects to the forward angle-bar 18of the rear line of pin-holding devices.

lt will be seen from the arrangement described that when the rock-shaft is rocked rearwardly, the link 35 of each of the described mechanisms will push rearwardly on the connecting angle barv 17 and conse- A quently cause a'rearward swing of the rear wings 16 of the' rear line of pin-holding devices, and that through the intermediary of the link 36, medially pivoted lever37, and the other link 38, the forward angle bar 18 will be acted upon so as to cause a forward swing of the frontwvingsy of the rear line of pin-holding devices. l also operate from 'the nain 'rock-shaft the rear wings of the nectingl arlink 39-'which extends forwardly 0f course, necessary second row of pin-holding devices, by conf yvices are swung rearwardly.

nected to the rear angle bar 19 of said second row of pin-holding devices, the result being that when the rock shaft is rocked rearwardly, la pull is exerted rearwardly on thevbar 19, and

which said bar is attached are swung rearwardly on their pivots.

In view of the fact that three sets of the mechanism just described are preferably employed (although as before stated only one set of such mechanism might be used andconsequently the rear .wings of the second row of pin-holding devices to successful results secured) I have onlyl deemed it necessary to describe one set thereof, and have indicated the several corresponding parts of the/two other sets by corresponding reference numerals. It is also, that the forward angle bar 20 of the second row of pinsholding evices be swung so as to produce a forward swing of the forward wings of said second row. To accom lish this, I provide links 40, 40 which are ivotally connected at their rear ends to the forward angle bar 18 of the rear row of pin-holding devices, and pivotally connected at their forward ends ,to the said.' angle bar 20. At is obvious that when there is a forward pushonthe angle bar 18 a corresponding push is' given, through the arms 40, to the forward angle bar 20 of the second row of inv-holding devices, and consequently the orward wings of said pinholding devices are swung forwardly on their pivots. One of the links 40 would no c doubt answer the purpose, but for the distribution of the strain, and for greater strength, l prefer to employ two of said links. It is also necessary that a rearward swing be given to the rear wings of the third line of pin-holding devices, and to accomplish this, I provide links-41, 41 which are pivotally connected at their rear ends to the angle bar 19 and' at their forward ends to the angle bar 21. lt is obvious that when theangle bar 19 is swung rearwardly by the.

action of the links 39, a pull is exerted in the same direction on the angle bar 21 by means of the links 41, and consequently the rear wings of the third row of pin-holding de? Only one of the links 41 might be provided, but l prefer,

for better' operation, and equalization of strain, to employ two of such linkse v The forward swing of the forward wings of the third row of pin-holding devices-is effectedby means of links 42, 42, which at their rear ends are pivotally connected to the angle bar 20, and at their forward ends are connected to the forward angle bar 22 of the forward wings of said row of wings.

v:in viewy of the fact that the angle bar 20 is thrown forwardly, the angle bar 22 will be moved in the same direction, through the intermediary of.l the links 42, and conse# quently the forward wings of the third rod ier , 59 zontal axial pills journaled in bearings in wardly. u

For effecting the rearward swing of the rear wing, of the single pin-holding device at the forward end of the platform, I provide a link 43 which is secured at its rear end to the angle barv21, andl at its forward'end toy the short angle bar 23. 'In view of the fact `that the angle bar 21 isl pulled rearwardly, the short angle bar 23 is; through the connecting link 43, pulled in the same direction, and consequently the front wing of the forward pin-holding device is thereby swung rearwardly.V l

For turning forwardly the front wing of the forward pin-holding device, I provide extensions 44, 44 to the links,42, and connect the forward ends of said" extensions to opposite ends of the angle bar 24. As the angle bar 22 moves forwardly when actuated, it will be obvious that the angle bar 24, through the described connection, ywill be moved in the same direction, and consequently the frontvr wing of the forward pinholding device will be swung forwardly.

Extending upwardly from the platform 8 are three tubular posts 4 5, two of said posts being located at the rear corners of the platform, and the third post atthel forward extremity of said platform. These posts pass freely' through eyes 46 formed at the ends of A'bracket arms 47, said bracket arms extending. from a wall, or other support. The up per ends of these tubularl posts telescopically fit short tubes 48 depending from the under side of an upper frame 49, and have a limited movement vertically in the tubes 48. rl.`he upper frame 49 is advisably of the same shape as the lower platform 8. Ropes 50, 50 and 50 arensecured beneath the platform 8 by any desirable means, asvby knotting the ends thereof, and these ropes are passed through openings 5l in the platform, `said openings being in registration with the tubes 4,5. These ropes are continued upwardly through the tubes and through the upperI frame, The two ropes' 50 which pass through the rear corner posts extend over pulleys 52, 52 which are mounted on horithe upper frame. rlhe said ropes arc then continued inwardly toward the center of the upper frame, then around horizontally mounted guide pulleys 53, 53, thence over pulleys 54, 54 at the rear end of tlieuipper frame, and finally connected to a common weight 55. The rope which extends through the forward tubular post 45 passes through 'the upperL frame` thence over a.

pulley 5G'near the forward end of said frame, then'ce continued rearwardly over another pulley 57 at the rear end .of the upper frame` and lthence .downwardly for connection to ythe weight 54.

Thenabove being Ia description of the construction of the apparatus, I will now de# scribe the operation of the mechanism.

lt will be understood that the weight is sufficiently heavy to exert a pull through 'the ropes 50 50 and 50 of sufficient force to maintain the platform 8 in a raised position, and at such height as to cause the lower ends ofthe wings 1G to just clear the upper ends of the pins 58 wlich are set on the floor '59. TheAveight is also sufficiently heavy as-not only to hold the said platform andthe mechanism carried thereby in this raised position, but also maintain the platform in a raisedy position when the additional weight of theypins retained in the pin-holding devieesis added thereto. The, wings 16 when not retaining or holding the pins,l are in their closed position, as illustrated in Fig. 4, being releasably locked in said position by means of the lug 32 of the dog or catch 3l engaging the recess 33. iVhen a game is to be played, the first step is to adjust the pills to the several pin-holdl ing devices. This is done by the alley boy -or attendant pushing the pins into engage-v ment with the holding devices, withy the base of eachpin pointing downwalylly, each pin being pushed until the base thereof is about flush with the lower ends of thevwings. The guides 14, of course, facilitate, this operation. Indeed, an alley boy or attendant may become so proficient as to he able to throw the pins into the different cages or holders` the' guides greatly facilitating the proper Ypositioning of each pin, base down. It will be noticed that rthe inner surfaces of the wings. are shaped to conform to theicontour of the 4sides of the pin. "When all the pinholding devices or cages are loaded` the attendant places his hands on the platform. preferably at the rear thereof, and pushes force to overcome the counteracting influence or effect. of the weight. The platform is `thus pushed downwardly until thc legs G0 depending from the under side of said platform contact. with the floor or surface 59.

or catch 31 is pulled toward the main lever 32 out of engagement with the recess 33, and consequently unlocking the lever 27, and permitting said lever to be turned. The lever is now turned bythe operator toward the rear of the platform. of rocking the rock-shaft 26 toward the rear. Vand with this rocking of said shaft,y all thc wings 16 of the several pin-holding devices or catches are swung on their Apivots to open position-in the manner herein before fully explained, and consequently the lpins are released, and-in condition to be left standing properlypos'itioned on the floor 59.

ward pressure on' the platform 8 is now removed, and the weight 54 will then 27. This has the effect of raising the lug This has the effect i Downioo downwardly on said platform with sufficient Vhen this occurs the upper arm ofthe dog in the platform and thereby normally hold the lever in a locked condition, and connechave the eEect of pullin 8 upwardly to such the upper ends of the pins. While the platform is thus raised, the cages Ymay be filled with another set of pins, so that when the pins of the first set, and which the platform were set up on the Hoor 59, are knocked down, they can be swept aside by the attendant, and the platform, loaded with the second setv of pins, immediately lowered, and

said second set of pins set up, without the ,attendant delay usually encountered between the knocking down of the pins and the re-v setting-of the same pins, as in the ordinary and most usual method.
